How to validate both Chinese (unicode) and English name?

Question

I have a multilingual website (Chinese and English).

I like to validate a text field (name field) in javascript. I have the following code so far.

var c         


        

Answer 1

var chkName = /\s/;

function check(name) {

    document.write("
" + name + " is ");

    if (!chkName.test(name)) {
        document.write("okay");
    } else {
        document.write("invalid");
    }

}

check("namevaluegoeshere");

check("name value goes here");

This way you just check if there's any white space in the name.
